В админке виртурилки есть опрос пинов.
Так вот. Плата лежит ровно, никого не трогает.
А при опросе самопроизвольно дергается 74 пин.
это нормально?
Какие-то шумы он ловит?

Ну это нормальное поведение.
Дело в том что это один из GPIO, используемых для системного светодиода (см. описание трех таких выводов ). Спойлер - это красный светодиод. :-)
В обычных мануалах и ссылках он отсутствует, но на приведенной вами страничке в админке выводятся все подряд номера GPIO, куда, в частности, попал и наш товарищ.
